|High wind levels have the potential to suspend particulate matter into the air. High levels of PM10 may pose an impact to public health. It is recommended that active children and adults, and people with respiratory disease, such as asthma, limit their outdoor activities.
Potential increases in PM10 concentrations may increase to moderate or unhealthy level.
|Imperial County Weather Synopsis
|Our string of sunny, warm days will continue into early next week with prevailing high pressure aloft and weak offshore flow at the surface. A weak trough briefly suppresses the ridge this weekend with weak onshore flow Saturday into Sunday morning. A shallow marine layer may bring low clouds and areas of dense fog to the coastal areas during this time, but the rest of the region will be largely unaffected. The ridge rebuilds over the Southwest Sunday night, with another sunny and warm day Monday with offshore flow
SYNOPSIS FROM THE SAN DIEGO OFFICE
Fair and warm weather will continue through early next week as high pressure and weak offshore flow dominate the weather pattern. A brief period of onshore flow could bring minor cooling and areas of low clouds and fog to the coast this weekend.
SYNOPSIS FROM THE PHOENIX OFFICE
A high pressure system will become nearly stationary over the region through early next week. This will result in dry and unseasonably warm weather, but with occasional high clouds
